Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct frequency tolerance and temperature range specifications. Confirm that the selected variant matches the required load capacitance and package dimensions for the target PCB footprint. Ensure compliance with RoHS directives if environmental regulations apply to the end product. Cross-reference the part number with the latest manufacturer documentation to avoid discrepancies in pinout or electrical parameters.

Crystals Selection Notes

Select this component when a 30 MHz reference signal is required for surface mount designs with limited vertical space. The 3.2 x 2.5 mm package size balances stability with board area efficiency. Consider the ±50 ppm tolerance and 5 ppm/year aging rate for long-term frequency accuracy requirements. Ensure the circuit design accommodates the specified load capacitance to maintain optimal performance within the -20°C to +70°C operating range.

Crystals Part Context

This component belongs to the Meritek MX3 series of ceramic SMD crystals. The series utilizes AT-cut quartz elements sealed in ceramic packages to provide excellent thermal stability and mechanical durability. These units are engineered for high-volume manufacturing environments, supporting both manual and automated placement techniques while maintaining consistent electrical performance across production batches.

Crystals Replacement Considerations

Direct substitutes must match the 30 MHz frequency, 20 pF load capacitance, and 3.2 x 2.5 mm package dimensions. Verify equivalent series resistance and aging rates to ensure system stability. Alternative parts from other manufacturers should be evaluated for compatibility with existing PCB footprints and thermal profiles.
